Application filed August 20, 1922. Serial No. 584,508.

Uur invention relates to die-casting machines having a movable ladle or carrier device in addition to a melting pot, irrespective of whetherthe die is operated by hand or power mechanism, and to machines, irrespective of how 'the metal is poured, in

which the die is power operated.

In the present type of die-casting machines whichuse a ladle that is caused to dip into a pot of molten metal. then to'deliver this metal under pressure into a die by being lifted from the pot and moved into contact with the. die opening, the entire weight of the ladle and its contents must be lifted by the operator. An object of this invention-is so to counterbalance the weight of the ladle that the exertion on the part of the operator is reduced to a minimum: An-

' which the ladle isjmoved bodily from the melting pot over to the die, the ladle was always kept connected to the compressed air supply either by a flexible coupling or by articulated tubing. This air connection has been a constant source of trouble, either by deteriorating or becoming clogged. In the present invention, 'the air connection has been entirely eliminated. We use a ladle which is completely disconnected from the pressure source when it is dipped into the melting'pot. @ur ladle is provided merely with an air inlet or opening which can be brought over into registration with the pressure source at the time when it is desired to eject the metal from the ladle into the die. Our ladle which is'normally open'tothe atmosphere at both ends, is dlpped into the melting-pot; When it has received its charge, the ladle is moved up into registration at one end with the compressed air supply and at its other endwith the opening of the die. The air supply is provided with an opening which isadjustable fboth horizontally and vertically. Also the ladle is so mounted that it can be adjusted horizontally, and vertically. These adjustments permit theuse of a die which hasconsiderable leeway in the location of its gate. A great advantage results from this feature in that it permits the location of the gate in the die where it is most suitable, instead of requiring the gate to be in practically one fixed position as isv necessaryrjn v the machines ot'the prior Another feature of our construction is the elimination of the comparatively long passage between the mouth of the ladle and the opening in the die as in prior machines. The mouth of our ladle is brought directly against the opening in the di Another object of this invention is to provide a construction in which the levers are all grouped on one side of the machine, making 1t convenient to be operatedby one man.

of the previous machines. We use a type out automatic clutch that has been long in success'lul use in'the mechanical'arts, a clutch such as is customarily used in power presses. One motion of the lever connects the power from. the flywheel to close the die. on the die has reached its closed positiony the die moving mechanism. is automatically disconnected trom the powersource. Another motion of the lever and the die is opened,

the power also being automatically cut off when the die has. reached itsopen osition.

In die-casting it is desirable to cap the molten metal at a.'predetermined constant tern erature. Heretofore in order to accomplis this a pyrometer has been used which T bit was customary to insert directly into the molten metal in themelting pot. Certain metals, especially'molten aluminum, badly deteriorate the metallic parts of the pyrometer with which they come in contact. In

order to obviate this, we have provided a pocket in the melting pot in which pocket lead or another substance notv harmful to the 'pyrometer islre t. The pyrometer is dipped into the meta ot this pocket out'of contact with the harmful metal adjacentinthe main body of the pot, enabling it to in- W) dicate the temperature and still be 'not subject to deterioration;

Other objects andjadvantages will become apparent ripen further reading of this specification an a studyoi the drawings.

In the accompanying drawings wherein is ill Our die is operated by a positive mechanical drive instead of fluid pressure as in many lll 2 meant? illustrated one embodiment of the invention, Fig. 1 is a side elevation of the machine, Fig. 2 is a plan view, Fig. 3 is a front elevation with the furnace and melting pot removed and Fig. 4 is a rear end elevation.

The melting pot 5 is set in furnace 6 which can be of any suitable type such as is well known in the art of die-castin Tn melting pot 5 is located a well 7 adapted to be filled with molten lead while the main cavity of pot 5 is filled with the metal to be cast. The pyrometer (not shown) is inserted in well 7 where its contact with the molten lead indicates the temperature of the adjacent metal in the pot. As explained above the use of a separate lead well is to prevent the deterioration of the metallic parts of the pyrometer which are attacked when in contact with certain molten metals as aluminum. The ladle or carrier device 8 is formed with a goose neck at one end in which is inserted a removable bushing or nozzle 9. The advantage of having a removable nozzle, such as 9 is that it is in this location where rapid deterioration takes place. lnstead of having to provide a new ladle 8 when worn at its mouth, a new nozzle 9 can be supplied. The ladle 8 is formed of two main portions. an upper and lower portion fastened together by screws 10. The lower portion of the ladle 8 which is subjected to the action of the hot metal is destroyed more rapidly than the upper portion and our construction permits the renewal of the lower portion when worn without having to replace the whole ladle. @f course it is to be understood that a ladle made of one piece also could be used in our machine excepting that the advantage just noted would be lost.

The upper portion of ladle 8 which is hollow, is fitted at its end with an adjustable nipple 11. A rib 12 (Fig. 1) is formed on the upper portion of ladle 8 which carries bosses 13 (Figs. 2 and The ladle 8 is swingingly mounted on trunnion shaft 14 which passes through bosses 13 and rib 12. Adjustable collars 15 are fastened on shaft 14- adjacent to bosses 13. By shifting collars 15 on shaft 14, a lateral adjustment of ladle 3 can be had. The ends of shaft 14c fit into boxes 16 which are adjustably mounted in rectangular frames 17 formed on the tops of arms 18.v The vertical adjustment of shaft 14 and hence of ladle 8 is accom plished by means of set screws 19 which retain boxes 16 in place in frames 17.

Normally ladle 8 which is hung on shaft 14: would tend to swing in a counterclockwise direction from that shown in Fig. 1. This swinging isprevented and the mouth of the ladle kept substantially horizontal by the bearing of roller 20, which is carried by rib 12, against the underside of the stationary cam 21. Cam 21 is so formed that ladle 8 is kept substantially verticalthroughout its motion from the melting pot to the die.

The lower ends of arms 18 are fixedly mounted on shaft 22 which is in turn mounted in suitable hearings in frame 23 of the machine.

Crank lever 2a is mounted and fixed to shaft 22 immediately next to the right hand arm 18 (Fig. 3). A. roll 25 is mounted on a stud 26 carried by crank lever 24. Another crank lever 27 is carried by shaft 22 adjacent to the left hand arm 18. Crank lever 27 has mounted on it a roller 28. Shaft 22 also carries counterweight lever 29 best seen in Fig. 1. Adjustably mounted on counterweight lever 29 is the counterweight 30. counterweight lever 29 and counterweight 30 are provided to'counterbalancc the weight of ladle 8.

lln close proximity to shaft 22 is mounted in suitable hearings in frame 23, shaft 31. Fixed to shaft 31 opposite crank lever 24 is lifting cam 32. Lover 33 is fixed to shaft 31 adjace; t o lifting cam 32. @n the other end of share 31 is fixed lowering cam Fig. 1 shows lever 33 in its lowest position with lifting cam 32 pressed and locked against roller 25. holding ladle 8 in its upper position, with its nozzle 9 in register with the opening of die 35 and its nipple 11 in contact with the compressed air nozzle 36. lit is important that ladle 8 be pressed against these openings with sufficient forceto resist the action of the air pressure when it is introduced into ladle 8 to force out the metal into the die. ltn order to insure this, the bearings of stud 28 in the forked arms of lever 24 are formed eccentric with the portion of said stud on which is mounted roller 25 1). By turning the head 37 (Fig. 3) formed on the end of stud 26, roller 25 can be brought nearer, or farther away from cam 32. thus accomplishing the adjustment of the pressure of ladle 8 against 0 the opening into the die 35 and air nozzle 33. l/Vhen lever is lifted, cam 32 is released from roller 25. Further lifting of lever brings cam in contact with roller 28 and lowers ladle 8 into the melting pot a as I shown by the dotted lines in Fig. 1.

Valve 38 which is connected to the compressed air supply (not shown) by means of pipe 39 is of a construction well. known to the art and hence requiring no detailed description. When lever 40 is pulled down, compressed air is admitted to ladle 8. When lever 10 is released, spring 41 returns it to its upper position shutting off the compressed air supply and opening up the 1n terior of the ladle to the atmosphere through an exhaust portin valve 38.

In order to insure proper registration of nipple 11 of ladle 8 with the compressed air supply, nozzle 36 is mounted in plate 42 which can be adjusted to various positions.

Plate 42 is held in position by screws 43 (Figs. 2 and 3), horizontal slots 43 in plate 42 permitting of lateral adjustment. For vertical adjustment T slots 45, into which the heads of screws 43 fit, are provided in bracket 46 of the frame.

The die consists of two main parts,.the fixed portion 35 which is fastened to the front frame 23 of the machine and the movable portion 47 which is fastened to plate 48. Plate 48 is provided with four sleeves 49 which are adapted to slide on four corre- Sponding guide rods 50. The guide rods are held at their front ends in frame 23 and at their rear in frame 51.

From the rear of plate 48 extends a bracket 52, through a hole in which wrist pin 53 fits. llrist pin 53 also fits in forked connecting member 54. Pitman 55 is screwed at its forward end into connecting member 54 while at its rear end it is screwed into a connecting member 56 which is provided with a bearing for crank pin 57. The ends of pitman 55 are oppositely threaded and provided with lock nuts 58. This permits of adjusting the distance between wrist pin 53 and crank pin 57 to suit varying thicknesses of the die parts 35 and 47.

Crank pin 57 is carried by crank disc 59 which is fixedly mounted on shaft 60. @n the other end of shaft 60 is fixedly mounted 61. Gear 62, which is fixed on shaft 63, meshes with gear 61.

The automatic pin clutch which is about to be described is one which is well known to the arts, being often found on power presses, where the throwing in of a lever brings about one operation of the press.

The automatic in clutch used in our machine consists as is usual of two parts, one part 64 which is fixed on shaft 63 carrying a spring actuated bolt 65, and the other part 66 which is loose on shaft 63 carrying pin 67. The clutch part 66 is formed integral gear 68 also loose on shaft 63.

Pulley wheel 69 adapted for belt drive is fixedly mounted on shaft 71. Pinion 70 which is also fixedly mounted on shaft 71 meshes with gear 68.

Lever 72 is fixed to the end of shaft whichcarries fixed at its other end the irregular shaped lever 7 3. A lip on lever 73 is adapted to engage the lower end of a spring actuated pawl 74. Normally pawl 74 is held by its spring 76 in engagement with one of the two notches formed in the periphery of crank disc 59 locking said disc against rotation. Another lip on lever 73 is provided with a slot which is adapted to slide over pin 77 carried by pawl 78. Pawl 78 is pivpted at one end on pin 79. When pawl 8 is in the position shown in Fig. 1, it is adapted to hold bolt 65 out of engagement with pin 67 (Figs. 1 and 4) which is in constant rotation, being driven by the pulley 69 through shaft 71 and gears 70 and 68.

Vl/ hen lever 72 is lifted from the position shown in Fig. 1, lever 73 is first caused to disengage pawl 74 from the notch in crank disc 59, the slot in lever 73 allowing it to rotate for a distance before it comes against pin 77. Further rotation causes lever 73 to depress pin 77 separating pawl 78 from spring actuated bolt 65. When bolt 65 is released, it shoots out into the way of the rotating pin 67. When pin 67 comes into engagement with bolt 65, clutch part 64 and gears 62 and 61 are rotated causing crank disc 59 to rotate. The operator will have by this time dropped lever 72 bringing pawl 78 up into its original position. Now when bolt 65 reaches pawl 78 it is pulled out from engagement with pin 67 thereby disconnecting the power drive. The dropping of lever 72 also released pawl 74 so that it springs in against crank disc 59 stopping said disc at the next notch. lit is thus seen that actuating lever 72 causes the power drive to turn crank disc 59 a half revolution while the clutch part 64 is given a complete revolution, gears 62 and 61 having the gear ratio of one to two.

When crank pin 57 is in the position shown in Fig. 1, the movable die part 48 is locked against its stationary mate 35, because pin 57 is at dead center and pawl 74 is in the notch in crank disc 59. This locking action is necessary to resist the pressure of the metal being forced into the die.

The operation of the machine is at follows: At the start of the cycle of operations, the die parts 35 and 47 are separated and ladle 8 is in the pot as shown in dotted position. The operator now lifts and releases lever 72, which causes the power drive, acting through the automatic clutch 64 and 66 and gears 62 and 61, to give crank disc 59 a half revolution, moving thereby the die part 47 to its mate 35. The operator'now pulls down on lever 33 bringing up ladle 8 into registration with the opening in the die part 35 and with nozzle 36 of the compressed air supply. By pressing-down hard enou h on lever 33, ladle 8 is locked into this position due to the shape of lifting cam 32. The operator next pulls down on lever 40 which admits compressed air or any other suitable fluid into the top of the ladle 8 forcing out a partof the molten metal contained therein between the die parts 35 and 47. Lever 40 is then released, spring 41 pulling it upward. This cuts oil the compressed air supply and opens the top of the ladle 8 to atmosphere through an exhaust" port (not shown) in valve 38. The operator then lifts and releases lever 72 which causes the die to open. The machine is now ready for the next casting operation.
